Perched on top of the Rockefeller Center, visiting Top Of The Rock is one of the best things to do in Manhattan if you love a good view. Now, there are quite a few viewpoints in the city, but for me, this is one of the classics. Plus, you get a picture-perfect view of the Empire State Building, too. Now, if you want to go, make sure to book your tickets in advance, especially if you want to check out the sunset from here. Tickets fill up faster for popular times (like the sunset slots) so book it before you arrive.
